Norway's unrepentant mass killer, Anders Behring Breivik, is now under arrest. And he should count himself lucky for -- if entirely undeserving of -- a penal system in that country that is among the cushiest in the world. There's no capital punishment, and the longest jail term allowed is 21 years

Prisoners spend a lot of time out of their cells; exercise is encouraged. And in Halden, not only is there clean air but personal trainers.
